What is the equation to solve the area of a semicircle?
Area of a semicircle = (pi*radius^2)/2
How do you find the area of a semicircle using pi?
To find the area of a semicircle, you first need the radius (r) of the semicircle. The formula for the area of a full circle is ( A = \pi r^2 ). Since a semicircle is half of a circle, you divide that area by 2: ( \text{Area of semicircle} = \frac{1}{2} \pi r^2 ). Thus, the area of the semicircle can be expressed as ( \frac{\pi r^2}{2} ).
How many cubic feet in a 12 inch by 12 inch by 1 inch area?
one twelfth. 1/12
What is the area of a sheet of 9-inch by 12-inch paper?
The area of a sheet of paper can be calculated by multiplying its length by its width. For a 9-inch by 12-inch sheet, the area is 9 inches × 12 inches, which equals 108 square inches.
How many 1 inch blocks in a 12 inch by 12 inch block?
Two measurements are indication of area. The area would be 144 square inches.

Area of a 12 inch circle?
A 12-inch circle has an area of about 113.1 square inches.
What is the area of an 6 x 9 inch oval?
A 6 x 9 inch oval is a 3 inch x 3 inch square with a semicircle of 3 inch radius at each end. The total area is, therefore, 9 + 9*pi = 27.3 sq inches. Note that an oval is NOT an ellipse.
What is the area of a circle that has a 12 inch diameter?
The area of a circle that has a 12-inch diameter is: 113.1 square inches.

What is the area of the semicircle if the length of the arc of a semicircle is 10 and pi feet?
It is 27.49 units.
What is the area of a sheet of 9-inch by 12-inch paper?

What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
What is the area of a semicircle when the radius is 21?
The equation for area of a circle is A=pi x R x R. A semicircle is half a circle, so we calculate the area of a circle and divide by 2. The area of the circle would be approximately 1384.74. Thus the area of the semicircle would be 692.37.
